EXCLUSIVE: Blumhouse continues to refine its micro-budget genre formula, and it looks like one evolving factor is the casts are getting better. Jason Blum’s division is negotiating with Isla Fisher, Ellen Barkin and Jim Parsons to star in Visions, a Kevin Greutert-directed thriller that Blumhouse International is selling at AFM. In the Lucas Sussman-scripted film, a pregnant woman joins her husband at his vineyard home and begins to have unsettling visions that get increasingly more realistic and terrifying.

Fisher’s coming off Baz Luhrmann’s The Great Gatsby, Barkin is starring with Robert De Niro and Edgar Ramirez in the Roberto Duran pic Hands Of Stone, and Big Bang Theory‘s Parsons wrapped Zach Braff’s Wish I Was Here. They are all repped by CAA. Barkin is additionally repped by Untitled after she signed there last week.
